Sixty-seven percent of Americans support same-sex marriage — the highest level in Gallup’s trend. In each of the past three annual polls, Gallup has recorded three-percentage point increases among Americans who say same-sex marriages should be legally valid. The current figure is up 40 percentage points from the 27% who supported gay marriage when Gallup first polled on the question in 1996.
These data are from Gallup’s annual Values and Morals poll, conducted May 1-10.
Some of the increases in support may be due to greater numbers of lesbian, gay, bisexual and transgender (LGBT) adults getting married in the U.S. Using data for all of 2017, Gallup has found that more than 10.4% of LGBT adults are married to a same-sex spouse. This means that Americans are more likely to know someone who has married a same-sex partner, and the visibility of these marriages may be playing a role in overturning some folks’ previously held opposition to their legal status.
Gay marriage became legal nationwide in 2015 upon the Supreme Court’s Obergefell decision. This came more than a decade after the first state, Massachusetts, had legalized gay marriage. In the years leading up to the decision, a patchwork of state laws were created for and against same-sex marriage.
